Vertical spiral wing type water metering device

Abstract

The invention relates to a vertical spiral wing type water metering device, which comprises a shell, a water inflow channel and a water outlet channel, wherein the water inflow channel and the water outlet channel are respectively horizontally arranged on two sides of the shell, a cavity is arranged between the water inflow channel and the water outlet channel, a metering component is vertically arranged in the cavity, the middle of the metering component is connected to an inside wall of the cavity in a sealing manner, the water inflow channel is communicated to the lower part of the metering component, the water outlet channel is communicated to the upper part of the metering component, the metering component comprises a filter water mesh, a lower fluid director, wing wheels and an upper fluid director, wherein the filter water mesh, the lower fluid director, the wing wheels and the upper fluid director are arranged successively back and forth from bottom to top; the metering component also comprises an edge side pressure reduction channel close to the inside wall of the cavity and an adjuster, size of the edge side pressure reduction channel can be adjusted by the adjuster, and volume of the water flow practically measured by the metering component can be further adjusted. In the vertical spiral wing type water metering device, practical volume measured by the water metering device can be adjusted through the edge side pressure reduction channel and the adjuster, therefore, measurement accuracy can be improved, moreover, installation and maintenance are very convenient.

Description

technical field [0001] The invention relates to a water metering device, in particular to a vertical screw-wing water metering device. Background technique [0002] In today's era of increasingly scarce water resources and higher requirements for water consumption measurement, water metering devices are becoming more and more important. The water metering device is a meter that measures the amount of water used by users. It is mainly used in the water supply industry and various water units to measure the cumulative flow of tap water flowing through the large-diameter pipe network system. For water supply and water units to monitor the operation of the water system , prevent water damage, rationally allocate and use water resources for cost accounting and other aspects play an important role. There are many types of large-caliber water metering devices, such as electromagnetic flowmeters based on electromagnetic principles, ultrasonic flowmeters based on ultrasonic principl...

AI Technical Summary

Problems solved by technology

Its disadvantages are: 1. The measurement accuracy is lower than that of the flowmeter; 2. A straight pipe section is required before the meter

Moreover, the current large-caliber water meters based on the spiral principle at home and abroad cannot compare with electromagnetic and ultrasonic flowmeters in terms of measurement level, and the price of flowmeters remains high.
